.ifo allwhom may concern.-

Be it knownfthat I, SYnNEY C. No'rr, a citizen of the United States, and a resident of IQhicago, Cook county, Illinois, have invented certain new and useful lm rovements I n ,Lose-Leaf Binders; and l do' ereb)T declare that the following is a full, clear, andexact idescription of the same, referencebeing had to the accompanying drawing? and to the d t ereon, which form a partof this specification.

This invention relates to improvements in loose-leaf binders of that class adapted to receive andfhldremovable sheets and adapted i 5 to be adjusted to admit of varying the capacity ofthe binder at will.- Heretofore the capacity of loose-leaf binders has usually been limited and capable of but slight expansion and usuallyconsiderable space in the zo binder is not available for use inasmuch as the insertion or removal of sheets necessitated the insertion ofthe fingers between the back edges of the sheets. The capacity of such devices has also been confined within owing to the inability to secure suicient ri idity of the bindin devices when extended eyond their norma limit.

The object of this invention is to provide a 3o loose-leaf binder adapted to afford a construction capable of being expanded to any desired extent and afordin positive means for locking either a sin le s eet in place or .any desired number of s eets.

3 5 t is a further .object to provide an auxiliaryA clamping-plate adapted for adjustment entirely independentl of the quantity of or number of sheets in t e binder and acting to 'riigidly clampthe same entirel7 independ` 4o ently of the width of the back o he binder.

It isialso an object to afford a 'closed sectional back forV the Hinder adapted to be variedin width by the insertion or removal of sections and so constructed as to dilord automatic locking means at each end of the back. The invention embraces many novel fea: tures; and itconsists in'the matters hereinf after described, and more full y pointed out and defined 4in the a ended c aims. 5o

Refcrrin first to Figs. 1 to 12, inclusive, the binder is s own in its most contracted form or that ada ted to contain a minimum quantity of the eaves or sheets and com rises, as shown, a strap vor plate A, which a ords the bottom clamping or binder late of the frame and to which is attached t e bottom cover. An u per bindin or clamping plate A correongs with sai bottom binding-plate A. ntermediate the said binding-plates A A is provided a back-section a, provided at each end'with an inturned flan e a', ada ted to af'- ord apart of the ends o the bin er-frame. Said upper binding-plate A is bent longitudinally to afford a depending back-flan e a, which extends downwardly along the acksection a and is ap roximatel of.V the same widthtthercwith. Xt each en of said upper bind' -plate A is provided an end late 11.5

ont

Fig. 18 is adetail view l lremovable back-section having a nut thereon IOO which ts'over the end ilaV es a of t e baclg through a vertical slot in the inwardly-turned end or flanges a of the back-section, as shown in Figs: 4 and 5, and permits the binding-plates to be drawn apart` Adjacent each end of the back-section a a clip or bracket a is secured, comprisin a strap of sheet metal bent to afford a cy indric bulb provided with a cylindric seat or bore eX- tending transversely and parallel with the lane of said back-section and supported at a istance therefrom and secured to the back plate by means of rivets or the like, as shown in Fig. 2, engaged through the outturned ends of the strap and the back. Secured on the top binding-plate A are downwardly-extending tubular impaling-posts B, which re ister with the bore of said brackets a5. s shown, each of said im aling-posts contains a coiled spring b, which ears against the inner end of a post-section b', which is brazed or otherwise secured in the brackets ct5 and is threaded at its outer end and extends throu h the bindin -plate A and is provided on t e outer end t ereof with an angular nut b". A threaded clamping-bolt C extends through the upper binding-plate A and is provided on the outenside with an angular head c and at the point where engaged 1n said binding-plate is of smaller diameter and engaged rotatively in place by a slotted platec, riveted to the late A. The lower end of the clampingolt is provided with a reversely-threaded extension c of smaller diameter, as shown in Fig. 1, adapted to engage in a nut c, secured to and beneath the binding-plate A. As shown in Fig. 12, said nut 1s transversely notched on opposite sides and said extension c is flattened on opposite sides, so that when said bolt is turned into one of its adjusted ositions it can be readily pressed inwar ly, partly through said nut, until the sheets' are engaged and may be then set up by rotating the same into engagement with the threads of the nut. Secured within the back frame thus formed is a follower or clam ing-plate D, of metal, flanged on its upper si e to afford sufficient rigidity and strength and notched at each end to receive the cylindric heads of the brackets a5. Said clampin -plate or follower is provided with a centra nut d, which engages the threads of the bolt when assembled, so that rotation of the clamping-bolt in One direction acts to move the clampinglate D downwardly toward the bottom binding-plate A, ressing the leaves or sheets contained in the inder upon the same, while rotation in'the other direction releases and acts to move said clamping-plate D u wardly to release the pressure from t e sheets. Inasmuch as the spring b acts to force the binding-plates A and A apart when said clamping-bolt() is reversed, slight movement of said olt is sufficient to engage or release the sheets. Should it be desired to increase the capacity of the binder, the top bindi -plate A', with its back a2, and the lower ack-section a, are released from the lower plate A by the removal of the nuts bl from the post-sections and longer or additional post-sections secured in place, which may be of any desired length. Additional back sections E and E are secured on the sectional or other posts e', which pass through clips e thereon, corres ending and of uniform diameter with the c ips a5 and affording a cylindric standard or rib rigidly braced on each back-section and extending lacross the back of the frame near each end thereof. The section E is secured u on the bottom binding-plate, and the plate is secured in a similar manner thereon. The removable back-section E is provided centrally with a clip or bracket e", corres ondin with the brackets or clip e or a6 an provi ed with internal screw-threads adapted to receive the reversely-threaded extension c of the clamping-bolt C, thus enabling the back frame to be extended to any desired width, while providing a solid or closed back for the book and ri id standard or rib to enga e the paper. T e follower or clamping-plate) operates as before described, moving u wardly or downwardly on the clamping-bo t C and exerting clamp-pressure u on the leaves or releasing the same, de 'en ent upon the direction of the rotation t ereof.

As shown in Fig. 13, latches may be provided at each end of the binder-frame, comprising a leaf-spring formed of a strip or plate of spring-steel ,or other suitable material F, rigidly secured on the end a of the upper binding-plate and provided with a boltf, which extends into a notch in the section a when the binder is closed. Said latches are so arra ed that when the u per bindingplate is rawn away from the ower plate to its farthest extent in opening the binder said ybolts ergage above the uppler margin of the inturne position, even should the s ring b in the tuv end a" and holdt e binder in open ular portions of the post e omitted. The under side of the bolt f is inclined to permit the u per bindinglates to be forced downwardllg),r to close t e binder. The latch F springs at once into locking engagement in t the desired pressure is secured.

For the urpose of holding a portion of the leaves in p ace While inserting new leaves the brackets e e of the back-section E and the ends of said section are a ertured in alinement to receive a lrod which extends through the said brackets at the rear oi the head of the same and engages the pile of sheets near their inner edge and acts to hold the greater part of the same from disarrangement when inserting or removing leaves, as shown in Fig. 16.

Obviously the covers may be secured on said binder in a variety of ways. As shown,

IOO

e notch in the end a when approximately estesa a strip of an suitable material H is secured upon each o the binding-plates and is a er- .,rial, such as leather or other suitable material h and h', is Wrailped around said stri s and extends forwar a desired finish. Should it be desired to a lford a round back for the volume, one or more removable back-sections E' are pro.

vided on the rear facev thereof with a convex strip e", affording the desired convexity for the back.

The o eration is as follows: The binder is adjusts as shown in Fig. l, for a minimum quantity. of the leaves to be secured therein, and it is obviously easy to rotate thebolt C before engaging the same in the nut of the bottom `bindinglate sufficient] to move the follower or c amping-plate ownwardly into position to engage even a single sheet should the same be inserted in the binder. It is also obvious that said followenor clampinglate can be adjusted to engag any desired) number of sheets Within the ll capacity of the binder, as shown in Fig. 1, by varying the position upon the screw-shaft before closing the binder. Whenl the binder is full, as shown in Fig. 1 one or more back-sections may be inserted, as before described, ormin a back of any desired Width, having ri id standards of uniform size to be engaged y the aper. l Inasmuch as the clampinglate can e adjusted, as before described, eit er a uantity of leaves but slightly greater than t ose before contained in the device or'suiiicient to fill the entire binder may be engaged in place.

he spring b 1n the tubular post B is not essential, as 1t is obvious that the springlatches F will serve to sup ort the up er binding-plate when the bin eris unloc ed for the insertion or removal of leaves and that downwardressure on said bindingplate will act to cllise the same by permitting the bolts of said latches to snap into suitable notches in the end plate in the back-section a.. The construction described affords a minimum and a maximum capacity beyond that possible for any other extensible ostbinder and alfords ready means for adustment of the clam ing pressure without relative movement o the up er and lower binding-plates. The use of t e rod G enables a portion of the leaves to be held fromrelative movement when the binder is unlocked, thus enablin the-o erator to insert new leaves with t e use o, one hand only. The

tubular section B of the binding-post may be desired manner en the bind-1 secured in an);T

ing-plates A. As shown, however, said plates are apertured to receive the ends .of said inding-posts, which are upset and expanded within said plate and the outwardly-'projecty on each side of t ev l cover-board h 1n the usual manner, aifordin carried on said binding-plates,

the back in alinement with the ing ends thereof are cleft and turned over, as l shown in Figs. 8 and 15.
